Wintertime Eye Safety in California: Protecting Your Eyes from UV Rays, Glare, and Dryness


While California may be known for its year-round sunshine and beautiful coastlines, the winter season brings with it a unique set of challenges for our eyes. From the low winter sun casting longer shadows to the chilly Santa Ana winds drying out our eyes, Californians need to be vigilant about their eye health during these cooler months.

Whether you’re a surfer catching the winter waves, a skier hitting the snowy slopes of Tahoe, or simply enjoying a walk in the park, it's essential to understand how the season can affect your vision.

This guide is here to help you navigate wintertime eye safety for you and your loved ones.

Understanding Winter UV Exposure

Many Californians may be surprised to learn that the winter sun can be just as damaging to the eyes as the bright summer sun. Winter sun can be deceptive. While the temperatures drop and the days shorten, the risk from ultraviolet (UV) rays remains ever-present. Contrary to popular belief, UV exposure isn't solely a summertime concern.

During winter, the sun sits lower in the sky, resulting in more direct exposure to UV rays, especially during the late morning and early afternoon. Moreover, snow, common in many winter landscapes, can reflect up to 80% of UV radiation, amplifying the potential for eye damage. This reflected light can cause a painful condition known as snow blindness or photokeratitis, akin to a sunburn for the eyes. Additionally, while cloudy days may seem harmless, clouds don't block UV rays effectively, meaning your eyes can still be at risk even on overcast days.

When thinking about Winter UV Exposure, consider the following:

  • Children and UV Rays: Children's eyes are more susceptible to UV damage than adults. Their clearer lenses can't filter UV light as effectively, making it vital to ensure they wear protective sunglasses even on cloudy winter days.
  • Elders and UV Rays: As we age, the risk for cataracts and other age-related macular degenerations increase. Consistent UV exposure can accelerate these conditions. Older adults should prioritize wearing UV-blocking eye wear.

Combating Glare

Whether it’s the reflection of the sun off the Pacific Ocean or off freshly rained-on streets, winter glare can be intense.

  • Driving and Glare: Wet roads and low sunlight can produce significant glare, impacting visibility. Polarized sunglasses can help drivers of all ages combat this glare, making for safer travels.
  • Snow Sports Enthusiasts: If you're heading to the mountains, remember that snow can reflect up to 80% of UV radiation. Snow blindness, or photokeratitis, can be a painful condition resulting from such intense exposure. Always wear snow goggles with UV protection when participating in your winter activities.

Winter Dryness and Your Eyes

The winter season, especially in Southern California, can be notoriously dry. These conditions can exacerbate dry eye syndrome. As temperatures plummet, the air becomes drier, stripping away the natural moisture from our environment, including the tear film that keeps our eyes lubricated. Indoor heating systems, while essential for warmth, can exacerbate the problem, reducing indoor humidity levels and creating an environment where our eyes can easily dry out.

The combination of cold, windy outdoor air and dry indoor heat can lead to a reduction in the quality and quantity of tears, leaving our eyes feeling scratchy, red, and uncomfortable. Furthermore, in wintertime, we tend to drink less water, further depriving our body and eyes of essential hydration. This seasonal dryness can be particularly challenging for those already prone to dry eye syndrome or those wearing contact lenses.

Taking measures to combat this seasonal discomfort becomes essential to ensure clear vision and eye comfort throughout the colder months.

  • For the Youth: Children might not communicate their discomfort, mistaking dry eyes for tiredness. Keep indoor environments humidified and encourage frequent blinking, especially during screen time.
  • Middle-aged to Older Adults: Hormonal changes can make this group more susceptible to dry eyes. Drink plenty of water, consider omega-3 supplements, and consult with an optometrist about artificial tears.

Winter may pose unique challenges for our eyes, but with a proactive approach, we can ensure optimal eye health during the colder months. Here are our practical tips to care for your eyes this winter.

  1. Stay Hydrated: Drinking plenty of water benefits not just your body but your eyes too. It helps maintain the natural salt balance in tears.
  2. Blink More: Especially if you're in front of screens a lot. Blinking helps spread tears evenly across the eye, preventing dry spots.
  3. Protective Wear: Always have a pair of 100% UV blocking sunglasses at hand. For sports or activities, consider safety goggles or sports eye wear.
  4. Regular Eye Check-ups: An essential aspect of winter eye safety is knowing the health of your eyes. Regular check-ups can catch any potential issues early on.
